Buyer-facing sourcing candidate for niacinamide / nicotinamide Vitamin B3 powder from a China-based supplier listing. The page contains conflicting identifiers: the title references niacinamide with CAS 59-67-6, while the product details show CAS 98-92-0 for nicotinamide and an unrelated CAS 9004-32-4 in the header. Overseas buyers should verify CAS, grade, assay, impurity profile, COA alignment, and export documentation before RFQ or sample approval.

Human review
Compliance notes
Do not rely on the listing title for identity confirmation due to CAS/name inconsistencies
Request latest batch COA, specification sheet, SDS, TDS, allergen statement where applicable, GMO/BSE-TSE statements if relevant, and certificate of origin
Confirm intended market compliance separately for food, feed, supplement, or industrial use; the supplier listing mentions FAMI-QS, ISO9001, HACCP, SGS, and CIQ, but certificate validity and product scope must be verified
Ask whether the supplied material is food grade, feed grade, pharma-related grade, or technical grade, and confirm applicable standard such as USP, FCC, EP, BP, or in-house specification
Confirm impurity testing scope, including related substances, residual solvents if applicable, heavy metals, arsenic, lead, cadmium, mercury, and microbiological limits for food/supplement applications
Confirm whether the product is classified as dangerous goods for the selected transport mode and request current SDS transport section for export booking
Check import requirements in the buyer’s destination market before purchase; no regulatory approval or market access guarantee is implied
Share target market, quantity, packaging scope, artwork status, delivery destination, and required documents so CHN Chemicals can prepare a cleaner supplier comparison.
